Cities are frequently viewed as passive participants to state and national efforts to solve the toughest urban problems. But the evidence suggests otherwise. Cities are actively devising innovative policy solutions and they have the potential to do even more. In this volume, the authors examine current threats to communities across the U.S. and the globe. They draw on first-hand experience with, and accounts of, the crises already precipitated by climate change, population shifts, and economic inequality. This volume is distinguished, however, by its central objective of traveling beyond a description of problems and a discussion of their serious implications. Each of the thirteen chapters frame specific recommendations and guidance on the range of core capacities and interventions that 21st Century cities would be prudent to consider in mapping their immediate and future responses to these critical problems. How Cities Will Save the World brings together authors with frontline experience in the fields of city redevelopment, urban infrastructure, healthcare, planning, immigration, historic preservation, and local government administration. They not only offer their ground level view of threats caused by climate change, population shifts, and economic inequality, but they provide solution-driven narratives identifying promising innovations to help cities tackle this century’s greatest adversities.

The former mayor of New York City and the former Sierra Club head present a manifesto on how the benefits of taking action on climate change can be real, immediate, and significant, explaining how cities, businesses, and individuals can make positive changes.

David Miller presents a compelling case that significant progress can be made at the local level by duplicating the actions of nine leading cities around the world.

Cities across the globe are growing fast. Today many are environmental nightmares with polluted air, excessive energy consumption and an absence of nature. But big cities don’t have to mean a dystopian future. They can be turned around to be powerhouses of well-being and environmental stability – if we empower women. This book is a unique collaboration between C40 and Friends of the Earth showcasing pioneering voices in the environmental and feminist movements. This book reveals just how women’s empowerment is critical to environmental sustainability. This book is a rallying call – for the planet, for women, for everyone.

A pointed argument that cities—not nation-states—can and must take the lead in fighting climate change Climate change is the most urgent challenge we face in an interdependent world where independent nations have grown increasingly unable to cooperate effectively on sustainability. In this book, renowned political theorist Benjamin R. Barber describes how cities, by assuming important aspects of sovereignty, can take the lead from faltering nation states in fighting climate change. Barber argues that with more than half the world's population now in urban areas, where 80 percent of both GDP and greenhouse gas emissions are generated, cities are the key to the future of democracy and sustainability. In this compelling sequel to If Mayors Ruled the World, Barber assesses both broad principles of urban rights and specific strategies of sustainability such as fracking bans, walkable cities, above-ground mining of precious resources, energy and heating drawn from garbage incineration, downtown wind turbines, and skyscrapers built from wood. He shows how cities working together on climate change, despite their differences in wealth, development, and culture, can find common measures by which to evaluate the radically different policies they pursue. This is a book for a world in which bold cities are collaborating to combat climate change and inspire hope for democracy even as reactionary populists take over national governments in the United States and Europe. It calls for a new social contract among citizens and municipalities to secure not only their sustainability but their survival.

"An audacious and concrete proposal…Half-Earth completes the 86-year-old Wilson’s valedictory trilogy on the human animal and our place on the planet." —Jedediah Purdy, New Republic In his most urgent book to date, Pulitzer Prize–winning author and world-renowned biologist Edward O. Wilson states that in order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet. In this "visionary blueprint for saving the planet" (Stephen Greenblatt), Half-Earth argues that the situation facing us is too large to be solved piecemeal and proposes a solution commensurate with the magnitude of the problem: dedicate fully half the surface of the Earth to nature. Identifying actual regions of the planet that can still be reclaimed—such as the California redwood forest, the Amazon River basin, and grasslands of the Serengeti, among others—Wilson puts aside the prevailing pessimism of our times and "speaks with a humane eloquence which calls to us all" (Oliver Sacks).
